Example 1:
aiming at the leveling method of the automobile interior trim leftover material, the utilization rate of the leftover material and the purity of the recovered material can be improved, and as shown in figure 1, the method is particularly set as follows:
the method adopts the existing hot press as hot pressing equipment, and utilizes the hot press to carry out hot pressing and flattening on the leftover materials, and the hot-pressed leftover materials are preferably in the same specification, and the method comprises the following steps:
step S1, a soft pad 2 is laid on the top surface of the base 1 of the hot press, and the soft pad 2 is preferably set to be a zero-degree silica gel pad with soft texture and good deformability. The size of the soft cushion 2 generally needs to be larger than the width of the leftover material to be hot-pressed, and the overlong leftover material is leveled by adopting a multi-time hot-pressing mode;
step S2, placing the leftover material 4 on the soft cushion 2, enabling the PET layer of the leftover material 4 to face downwards and to be in contact with the soft cushion 2, and enabling the EVA layer of the leftover material 4 to face upwards to the hot pressing plate 3;
step S3, controlling the hot pressing plate 3 to move downwards to contact the EVA layer of the leftover material 4, then controlling the hot pressing plate 3 to continue to move downwards to press the PET layer of the leftover material 4 against the soft cushion 2 to improve the flatness of the leftover material 4, and heating the leftover material 4 by the hot pressing plate 3 in the pressing process to soften the EVA layer of the leftover material 4 so that the EVA layer can be leveled;
step S4, keeping the hot pressing plate 3 still, and continuously heating the EVA layer of the leftover material 4, wherein the EVA layer of the leftover material 4 is required to be kept not to be melted;
and step S5, controlling the hot-pressing plate 3 to move upwards and to be separated from the hot-pressed leftover material 4 after the required hot-pressing time is reached.
In step S3 and step S4, the heating temperature of the hot press board 3 is generally set to be constant, the temperature value is set to be 110 ℃ to 150 ℃, the total heating time of the EVA layer of the hot press board 3 contacting the scrap 4 is set to be 85S to 170S according to the difference of the temperature, and multiple sets of parameters can be obtained. Such as:
the first set of parameters, the heating temperature of the hot press plate 3 was set to 110 ℃ and the total heating time was set to 170 s.
The second set of parameters, the heating temperature of the hot press plate 3 was set to 120 ℃ and the total heating time was set to 150 s.
The third set of parameters, the heating temperature of the hot press plate 3 was set to 130 ℃ and the total heating time was set to 120 s.
The fourth set of parameters, the heating temperature of the hot press plate 3 was set to 140 ℃ and the total heating time was set to 90 s.
In the fifth set of parameters, the heating temperature of the hot press plate 3 was set to 150 ℃ and the total heating time was set to 60 seconds.
The fourth set of parameters is preferred because the EVA layer with the leftover material set in the fourth set of parameters is not softened too much even heated to 140 ℃, has short heating time and has high processing efficiency.
And taking down the flattened leftover materials after the five steps, taking the leftover materials needing hot pressing again, and repeating the steps S2 to S5.
When the method is adopted, the cushion 2 is arranged on the top surface of the base 1 of the common hot press, so that the PET layer of the leftover material 4 is pressed against the cushion 2. Because cushion 2 has certain elasticity and can warp, the position that cushion 2 and leftover bits 4 take the lead to the contact can the pressurized invagination, the position evagination relatively is then not contacted, so can make cushion 2 better, earlier fully contact with the last concave part of leftover bits 4, later make everywhere of leftover bits 4 unevenness receive more abundant extrusion and heating, improve the roughness of leftover bits 4, so that, leftover bits 4 also can obtain better roughness when receiving less extrusion force, can reduce the degree of depth that the PET layer impressed the EVA layer, reduce the separation degree of difficulty of leftover bits, improve the purity of separation material. The zero degree silica gel can obtain fine deformation when being stressed and can fully contact with the PET layer of the leftover bits 4, so that the leftover bits 4 obtain better flatness.
In order to improve the hot-pressing quality of the leftover material, it is necessary to ensure that the pressure of each hot-pressing is maintained within a certain range, and preferably, the above purpose is achieved by setting the maximum stroke of the hot-pressing plate 3, after the step S1 is completed and before the step S2 is performed, the minimum gap between the hot-pressing plate 3 and the cushion 2 is adjusted, the minimum gap is the same as the thickness of the leftover material 4 to be hot-pressed, generally between 3 mm and 5mm, and corresponding adjustment is made according to the leftover materials with different specifications, for example 4 mm. Minimum clearance between hot pressboard 3 and cushion 2 is adjusted according to the thickness of the leftover bits 4 of wanting the hot pressing in advance, makes leftover bits 4 can receive appropriate extrusion pressure degree, does not lead to making the PET layer by the EVA layer of impressing too much when the EVA layer of leftover bits 4 softens to be favorable to the later stage to separate.
Example 2:
the embodiment is further optimized on the basis of the above embodiment, and in order to further better implement the invention, the following method is particularly adopted:
before step S4 in example 1, the PET layer of the leftover material 4 was sprayed with water to lower the temperature, and the temperature of the sprayed water was lower than the heating temperature of the hot platen 3. The water spray can adopt the shower nozzle from the side to face PET layer water spray, also can follow 2 spouts on the PET layer through the cushion under, for example be provided with a plurality of water courses 5 that link up from top to bottom at cushion 2, water course 5 is connected with the water source, makes the surface of cushion 2 be stained with water or spout water smoke or water column through 5 water sprays of water course, drenches the PET layer, realizes the PET layer cooling to leftover bits 4.
When the method is adopted, the water is sprayed to the PET layer of the leftover material 4, so that the connecting belt of the PET layer and the EVA layer can be cooled, one side of the EVA layer connected with the PET layer is not excessively softened, the PET layer can be pressed into the EVA layer less, and later separation is facilitated.
Example 3:
the embodiment is further optimized on the basis of the above embodiment, and in order to further better implement the invention, the following method is particularly adopted:
can also be less than the leftover bits after the hot pressing through a temperature and colding the cold pressing board to the leftover bits after the hot pressing after step S5 and coldly press, the cold pressing board can be the component of another a set of not heated hot press, and the cold pressing can promote its cooling rate to the leftover bits and improve production efficiency, and the cold pressing board is pressed and also can be prevented its cooling deformation on the leftover bits, if the size of cold pressing board is greater than the size of leftover bits then also can place the leftover bits and stick up the limit when cooling.
In the cold pressing process, the cold pressing plate is generally at the temperature of room temperature, and the cold pressing time is 5-15s from the time when the leftover materials are pressed on the silica gel pad. The heating temperature is generally controlled at 140 ℃, the total heating time is controlled at 90s, and the cold pressing time is generally controlled at 10 s; the heating temperature is controlled at 110 ℃, the total heating time is controlled at 170s, and the cold pressing time is generally controlled at 5 s; the heating temperature is controlled at 150 ℃, the total heating time is controlled at 60s, and the cold pressing time is generally controlled at 15 s.
When the method is adopted, the cold pressing can promote the cooling of the leftover materials, the production efficiency of flattening the leftover materials can be improved, meanwhile, the cold pressing can also prevent the leftover materials from deforming in the cooling process so as to keep the flatness, and meanwhile, the leftover materials are prevented from warping when being cold pressed so that the shape of the leftover materials is unified, and the later-stage large-batch separation is facilitated.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
